ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight

Standards Program
The Standards Committee is responsible for the development and maintenance of voluntary consensus standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology.

In an international industry, regulators cross the border too
Since nuclear physics works the same in Ontario as it does in Tennessee, the industry has been trying to create a reactor that can be deployed on both sides of the border. Now, the Nuclear Regulatory Commission and the Canadian Nuclear Safety Commission have decided that some of their rulings can cross the border too.
Uranium Chemistry Tutorial
December 8, 2020|10:30AM–12:00PM (11:30AM–1:00PM EST)
Available to 2020 ANS Virtual Winter Meeting Attendees
ANS Members, please log in to watch this webinar.
This is part four of a nine-part tutorial series exclusively available to 2020 ANS Winter Meeting attendees.
Examples where chemistry has unexpectedly impinged (or might have impinged) on criticality control are explored.
Case 1: How poor engineering altered the chemistry of a dissolver system and caused an unexpected criticality hazard… or how a lack of engineering know-how fooled the chemists.
Case 2: How a criticality safety improvement made things less safe as chemistry triumphed over physics.
Case 3: How chemistry fooled even the chemists.
